Monitor lost all sound

[NicoleSaylor]

I have had this desktop for over a year and have always been able to play audio through the monitor. Never had speakers connected. When I turned my computer on today it says "no output devices found" and will not play any audio. I have been trying to fix this for hours with no luck. Cannot get in touch with anyone from HP. I have windows 11 if that means anything.

@NicoleSaylor, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

If your HP desktop is showing "no output devices found" and won't play any audio, you can follow these steps to troubleshoot and resolve the issue:

Check Connections:

• Make sure the monitor is properly connected to the desktop.
• Ensure the monitor's audio cable (if separate from the display cable) is securely plugged in.

Update Drivers:

• Update your audio drivers. You can do this by going to Device Manager, finding "Sound, video and game controllers," right-clicking on your audio device, and selecting "Update driver."
• Check for updates for your graphics card as well, since audio over HDMI is managed by the graphics card driver.

Set Default Playback Device:

• Right-click the sound icon in the taskbar and select "Playback devices."
• Ensure that the monitor is set as the default playback device.

Windows Update:

• Check for any pending Windows Updates. Sometimes these updates can resolve driver issues.
• Go to Settings > Update & Security > Windows Update and select "Check for updates."

HP Support Assistant:

• Use HP Support Assistant to check for and install any updates recommended for your system.

Restart and Reconnect:

• Restart your computer and reconnect the monitor.

Check Audio Settings:

• In Windows Settings, go to System > Sound, and make sure the correct output device is selected.
